How to judge the fault of tank semi trailer from tire wear

Oil tank semi-trailer wheel every day and rough road depth "kiss", wear is inevitable, but you can not therefore take the tire wear lightly, because sometimes can be found from the tire wear degree of the car hidden fault, generally speaking, if the car has no problem, tire wear should be uniform, If your car tire wear is not uniform, it may be a problem, let's take a look at several common tire abnormal wear phenomenon and solutions:

1. Early wear of the central part of the tank car tire: the main reason is too much air. Proper increase of tire aeration can reduce tire rolling resistance and save fuel. But when the aeration is too large, it will not only affect the vibration damping performance of the tire, but also make the tire deformation is too large, and the contact area with the ground is reduced. Normal wear can only be borne by the central part of the tread, forming early wear. If wide tires are used on narrow rims, they will also cause early wear on the central part.

2. Excessive wear on both sides of the tank car tire: the main reason is insufficient ventilation, or long-term overload driving. When the aeration is small or the load is heavy, the contact surface between the tire and the ground is large, so that the two sides of the tire work with the ground and form early wear.

3. Excessive wear on one side of the tank car tire: the main reason is the misalignment of the front wheel. When the camber Angle of the front wheel is too large, the outside of the tire forms early wear, and when the camber Angle is too small or not, the inside edge of the tire forms early wear.

4 tire tread zigzag wear: the main reason is the tank car front wheel positioning adjustment or improper position of the front suspension system, loose ball head, so that the normal rolling wheel sliding or driving wheel positioning is constantly changing and formed tire zigzag wear.

5. Large amount of individual tire wear: the suspension system of individual wheels is abnormal, the bending of supporting parts or the imbalance of individual wheels will cause the early wear of individual tires. In this case, the positioning of the worn wheel, the operation of the independent suspension spring and the shock absorber should be checked, and the cycle of wheel transposition should be shortened.

6. Alopecic wear of tires: the reason for alopecic wear on individual parts of tires is poor balance of tires. When the unbalanced wheel rotates at high speed, the force of individual parts is large, the wear is accelerated, and the steering is not smooth, and the handling performance becomes worse. If a particular speed direction is found in the driving when there is a slight shake, it should be balanced on the tanker wheel, in order to prevent the appearance of bald wear.
